Satellite navigation is primarily a high-precision tool for determining the location coordinates of physical objects. You can find the desired objects using modern navigation systems almost anywhere in the world. Actively developing modern satellite systems are able to provide extensive coverage for the transmission of accurate navigation data.
What is satellite navigation?
Satellite navigation systems are a wide range of electronic equipment and hardware in the form of a combination of space and ground equipment.
Navigation is a tool for determining the coordinates of the geographical position of objects. However, the most modern satellite navigation tools allow you to almost accurately determine parameters such as speed or direction of movement of the object and so on.
Navigation systems are based on orbiting satellite constellations, which may contain from two to several dozen satellites. Their main task is the exchange of radio signals between themselves and ground control systems. In turn, the client equipment of users is used to determine the necessary coordinates based on information received from navigation control centers.
The principle of operation of the satellite navigation system
The operation of satellite systems is based on determining the distance from the satellite to the antenna of the object whose coordinates must be calculated. A conditional map of the location of all the satellites in the system is known as an almanac. Most satellite navigation receivers are able to store such a map in memory and instantly receive the necessary data. Thus, navigation programs based on the geometric construction of coordinates allow you to calculate the exact position of the object on the map.
Personal satellite navigators
Modern personal navigators are high-tech devices designed not only to receive satellite navigation data, but also to provide the user with rich multimedia capabilities.
In combination with subscriber equipment with specialized software, personal navigators provide opportunities for monitoring both stationary objects and vehicles.
If we talk about drivers of vehicles, then for them navigation is, first of all, the opportunity to receive detailed recommendations regarding the selection of the most successful routes, following which allows you to optimize fuel consumption and significantly reduce travel time.
Prospects for the development of satellite navigation systems
Currently, satellite navigation is a system that is globally used for cartographic purposes. Most GPS navigation data is now controlled by the US military. Therefore, from year to year, the deployment of alternative systems where the European project “Galileo” and the Russian “Glonass” look the most pressing issue for the world community .
Based on the opinion of marketers, it can be argued that the coming decades promise a significant development for the navigation services market. Developers of projects in the field of satellite navigation also hold similar views. This is confirmed by the data of numerous research centers, which note the growing demand for navigation services among owners of portable digital devices.
